Hybrid memory systems with cache management

Plain English Translation

This invention relates to a memory module designed to optimize data storage and retrieval in computing systems. The module addresses the challenge of balancing performance and power efficiency by integrating different types of volatile memory. The module includes a first volatile memory and a second volatile memory, each serving distinct roles in data handling. The first volatile memory is configured to store data in a high-density, cost-effective format, while the second volatile memory is optimized for low-latency access. The module further includes a controller that manages data transfer between the two memory types, ensuring efficient operation. The first volatile memory is implemented using dynamic random-access memory (DRAM), which provides high storage capacity at lower cost but requires periodic refreshing to retain data. The second volatile memory is implemented using static random-access memory (SRAM), which offers faster access times and does not require refreshing, making it ideal for high-speed operations. The controller coordinates data movement between DRAM and SRAM based on access patterns, prioritizing frequently accessed data in SRAM to reduce latency while maintaining overall system efficiency. This design enhances performance for applications requiring both large storage capacity and rapid data access.
